From the One Page Wars game series.

Take the part of a local fire commander and allocate your limited resources to attempt to halt and extinguish a fire sweeping through the valley. You have at your disposal three firefighter units, a fire jumper unit, and a fire suppression aircraft. You may also use "backburn" units to halt the spread of the fire. If you lose any of your firefighters before the entire fire is extinguished, the game is a loss.
